Blackjack table

Total 20 is a very strong hand against a dealer 3, so standing maximizes expected value. Splitting tens or doubling would risk a winning hand without enough upside.

Hard 10 versus dealer 7 is a strong double-down spot; doubling maximizes expected value by getting one more card at the optimal bet size.

Dealer shows a 6, which is a bust-prone upcard, so standing on 15 is the correct basic strategy play.

Dealer shows a 6, a bust card, so standing on 16 is the correct basic strategy play.

Hard 10 versus dealer 2 is a strong double per basic strategy, maximizing expected value with the fixed base bet.

Standing on 20 is the optimal play against a dealer 3, as doubling or splitting would risk a strong made hand.

With a hard 13 against a dealer king, hitting is the correct basic strategy since the dealer is likely to make a strong hand. Doubling is too risky with a low total.

With a hard 14 against a dealer 8, hitting is the best play to improve the hand; standing is too weak and doubling risks busting with only one card.

Soft 15 vs dealer King is a clear hit; doubling would risk too much against a strong upcard, and standing is too weak.

Soft 16 is too weak against a dealer 10 upcard; hitting gives the best chance to improve to a making hand.

Stand with a total of 20; only a dealer 21 beats it, and the dealer upcard is a King, making a bust or a 21 unlikely enough to stand.

Soft 19 is a strong made hand, and with the dealer showing an Ace after a no-blackjack peek, standing avoids the risk of turning it into a stiff total.

Total 9 vs a dealer King is a losing situation, and doubling is only correct against dealer 3-6. Taking a hit gives the best chance to improve the hand.

Total 19 is a strong hand against a dealer King upcard; hitting risks busting, and the dealer must draw to 17 or better, so standing maximizes expected value.

Hard 6 against a dealer 8 is a losing hand; hitting gives the best chance to improve to a total that can beat the dealer's likely 18. Doubling is too risky with such a low total.

Soft 17 is a weak hand against a dealer 8; hitting gives a chance to improve to 18 or better without much risk of busting immediately.

Hard 13 against a dealer 8 is below the threshold to stand; hitting gives the best chance to improve without excessive bust risk.

With 15 against a dealer 8, standing is too weak since the dealer likely makes a made hand; hitting gives the best chance to improve.

Pair of 5s totals 10, which is not strong enough to double against a dealer 10. Splitting 5s is also incorrect, so hitting gives the best chance to improve.

With a hard 17 against a dealer's Jack, hitting risks busting with any card above 4, and the dealer must draw to 17 or better, so standing is the safer play to preserve chips.

Dealer shows a 2, a weak upcard, so standing on hard 15 is the basic strategy play and avoids unnecessary risk of busting.

Dealer shows a 4, a weak upcard, so standing on 12 is the optimal play to let the dealer bust.

Soft 15 is too weak against a dealer 10 upcard; hitting gives the best chance to improve without the risk of doubling into a strong dealer hand.

Dealer shows a 10, and soft 18 is not strong enough to stand; hitting improves the chance of reaching 19 or higher while a bust is less likely.

Hard 16 against a dealer 10 is a losing hand, but standing loses more often than hitting, so I take a card to try to improve.

Dealer shows a 6, a likely bust card, but my 12 is below the safe standing threshold and hitting gives a good chance to improve without much risk of hurting the hand.

Hard 18 beats a dealer 6 upcard often enough; hitting risks busting a made hand. Standing is the correct basic strategy play.
